Body Material

  • Ductile Iron for general applications.
  • Stainless Steel for increased corrosion resistance.
  • Cast Iron for water and low-pressure applications.

Disc Material

  • Stainless Steel for corrosive environments.
  • Ductile Iron with epoxy coating for improved durability.
  • Aluminum Bronze for seawater applications.

Seat Material

EPDM, NBR, PTFE for chemical compatibility and leak-tight shut-off.

End Connections

Lug-type body for easy installation between flanges, with bolt-through design for secure mounting.

  • Lug Type Design: The lugged body features threaded inserts, allowing bolts to secure the valve between flanges. This design supports one-sided flange connection and enables pipe removal downstream without disturbing upstream connections.
  • Quick Operation: A 90-degree rotation of the handle or actuator opens or closes the valve, providing fast and efficient flow control or isolation.
  • Bi-Directional Flow: Designed for flow in both directions, the valve ensures flexibility in piping systems.
  • Disc Options: Available in materials like stainless steel, ductile iron, or coated to provide resistance to corrosion and wear, ensuring compatibility with various media.
  • Seat Options: Soft-seated with elastomers like EPDM or PTFE to ensure leak-tight shut-off, or metal-seated for higher temperature or abrasive applications.
  • Compact and Lightweight: The design is compact and lightweight, making it easier to install and requiring less support compared to other valve types.
  • Corrosion Resistance: Available in materials such as ductile iron, stainless steel, and other alloys to withstand harsh environments and corrosive media.

Testing & Certification:

  • Hydrostatic testing in compliance with API 598.
  • Fire-safe design available as per API 607 for high-temperature applications.
  • ISO 9001 certified manufacturing process.
